SLEEP

Why? During the deep stages of Non-REM sleep, the body repairs and re-grows tissues, builds bone and muscle, and strengthens the immune system. During REM sleep we dream. Dreams probably take part in unconscious conflict resolution, memory consolidation.

BE UNDER NATURAL LIGHT

Why? Serotonin (“feel good” chemical in the brain) is produced more under direct sunlight. Melatonin (“sleep well” chemical) is produced in the dark hours. Circadian rhythm (day-night cycle) can be disturbed in artificial light or dark. How? Go outdoor whenever you can, even if it’s just 10-20 minutes. Arrange your workplace near the window. In artificial light: try therapy lamps.
